METHOD FOR GENERATION AND AUTHENTICATION OF ELECTRONIC DIGITAL SIGNATURE THAT CERTIFIES ELECTRONIC DOCUMENT Russian patent published in 2009 - IPC H04L9/14

Abstract RU 2369973 C1

FIELD: information technologies.

SUBSTANCE: invention is related to the field of cryptographic devices. Substance of invention consists in the fact that method for generation and authentication of EDS includes the following sequence of actions: secret key is generated in the form of multi-digit binary number (MBN) x, secret key is used to generate open key Y in the form of MBN size vector w x w, where 2≤m<32, electronic document (ED) is received, represented by MBN H, depending on received electronic document and on value of secret key, EDS Q is generated in the form of two MBNs, depending on Q, Y and H, the first A and second B authenticating MBN are generated, MBN A and B are compared. When they parametres coincide, conclusion is made on authenticity of electronic digital signature.

EFFECT: higher efficiency of electronic digital signature (EDS) algorithms without reduction of its resistance level.
